This article argues that although the lives of young homeless people are characterized by high levels of mobility, when examined closely movement is also revealed as heavily restricted. While a network of agencies moves the young people around the city, the official borders of borough councils and the non‐official territories of young people feed into an experience of London as a series of exclusionary bounded areas. Within the accounts of the young people, mobility is talked of as a resource but also in terms of loss and dislocation. The article argues for going beyond the opposition of mobility/fixity in order to examine how some people become fixed in mobility.
